Hi, My name is***** can follow up as needed on here. Professionals are not employees of the site but users of the site and help on here as time allows depending on their daily schedule. I am not available for phone calls. If the site flags for a call, you can either disregard it or your call request will be posted for other professionals who may be logged into the site at the time to accept your request offer if they choose to do so.Sorry to hear that you are having these problems with this tractor sourcing parts. You will want to access the engine ID tag on the engine itself and get that model and serial number information to be certain that you get the proper head gasket and parts. You would then call them back with that information. There used to be a JCB parts catalog fully available online a couple years back but that has since changed and seems to go through a dealer network now. Look on your valve cover or side of the engine block for an engine ID tag or any stamped numbers. You may have to clean any dirt or grime off that  could be covering the tag or numbers. Once you have them, it is those numbers that you will want to provide to your JCB dealer to get the proper parts. I hope you find this information helpful. Reply back with the results of these checks if any further help is needed. It's a pleasure to help anyway I can.
